Application filed larch 9, 1907. Serial No. 361,643.

To all whom it may concern:

Be it known that we, ALEXANDER WIN- TON and HAROLD B. ANDERSON, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have'invented certain new and useful Imrovements in Carburetors, of which the folowing is a specification, reference being had therein to the accompanying drawing.

This invention relates to'improvements in carburetors, andisfor-use in connection with explosive motors for the purpose of furnishiega uniform explosive mixture to motors of d erent types and-involves theprinciple of operation wherein-a body of fluid is maintained within the air passage for surface carburization of slowly moving volumes of air, and to effect as ray carburization of the rapidly moving vo umes of air.

those t s of motors which limit the movement 0 t e inlet valves and cause them to act as a throttle for controlling the speed and power of the engine, the air passing to the motor even at its lowest speed passes through the carburetor in pulsating waves, whereas in that type of motor having a throtassage-way between the carbureter and t e engine, and in which the inlet valves are mechanically opened wide, the intervening throttle causes the air to pass through the carburetor when the engine is running slow, at low though constant velocities, and more difliculty is encountered in causing the slow but constantly moving volumes of air to be properly carbureted by surface carburization.

The object of the present invention is to construct a carburetor of the type hereinbefore mentioned which is so constructed that the air which is moving in slow but constant velocities is caused to travel in contact with the exposed body of volatile fluid and thereby cause 1t to be properly carbureted for slow speeds of the second type of motors, as well as the first type.

Referring now to the drawings, Figure 1, is a view of the carburetor embodying the presentlmprovement with the air passage shown in ion 'tudinal section. Fig. 2, is an edge view 0 the movable or swinging deflector for the air passage. Fig. 3, is an edge view of the deflector.

Referring now to the drawings, 1 is a fluid chamber for the asolene, and in which the fluid 1s maintaine at-a predetermined level in any of the well known ways, which need not be here described, to enable this improvement to be understood. The gasolene is maintained at the level indicated and marked in Fig. 1 by dotted line, and the words Fluid level. From this it will be seen that the maintained level of the chamber 2 is such thatthe fluid will flow by gravity through the passage-way 2 into the air assage 3, and a body of fluid maintained wit n this air assage. The ra idity with which the liquid will flow througii the opening 2 in the o eration of the carburetor may be regulated y a valve 4.

This carburetor is designed more particuposes it is here s 10WI1 adjacent the outlet end of the passage 3, as indicated at 12. As previously stated, in this class of motors the air passes through the carburetor at constant velocities, and more especially is this true when the throttle 5 is nearly closed for the pur ose of causing the engine to run slow.

, or the purpose of causing the volumes of air which move through the passage-way at slow, but constant velocities to be properly carbureted by surface exposure of the fluid 8c thereto, a deflector 6 is placed in this passage-wa and this deflector is arranged to be moved y the influence of the air passing throifihgh the passage-way, when its velocity is su cient to move it. may be arranged in many ways,- the form selected for illustrating the princi 1e herein disclosed is a swinging deflector aving its upper end loosely ivoted at the point 7 w 10b is located at t e upper wall of the passage 3. This deflector is declined in the direction of the travel of the air through the passage 3, whereby the air, when it has reached a sufficient velocity, will have a tendency to lift it. is placed with its lower and free end adjacent the oil outlet 2, and is provided with a cutawa portion to form a passage-wa y 8 direct y at the point of oil exposure. he 0 eration of this deflector, is to cause t e slowly but constantly moving volumes of air to pass through the passage 8, and in direct contact with the bod of surface exposed fluid. The deflector 18 made in the form here shown of a weight to maintain the posi- While this deflector 90 As shown, this deflector 100 tion shown in Fig. 1, when the engine is running at its minimum speed, and thus cause all of the air to pass adjacent and in contact with the surface exposed fluid, and to pick up and cause a proper carburization thereof.

The opening in the deflector is of a size to allow a sufficient air to pass therethrough when in the position shown in Fig. 1 for the very lowest motor speed, as when the motor is not under load, and the deflector is of a weight suificient to maintain this position with the air passing through at its lowest velocities. the opening and the weight of the deflector are fixed quantities for a motor of a given bore and stroke. To add to the weight of the deflector, and to facilitate the adjustment of its weight by removing a portion thereof,

I it is provided with the longitudinal ribs 9,

it be ng made in thefirst place of a Weight which may possibly require some lightening, though it will be understood that the proper weight of deflector having been once determined for a motor of a given size, by careful manufacture it could be duplicated and thus prevent the necessity'of adding to or taking therefrom. When the throttle is open sufficiently to require more air than can pass through the cut-away portion 8, the deflector will be raised sufficiently to permit this in creased volume of air to flow through the passage 3, and when the volumes of air passmg through the passage 3 are of such quantity that they require more gasolene than is furnished by the ex osed surface, or in other words, pick up or a sorb more oil than flows through the opening 2 to the passage 3, then the carbureter becomes a jet carbureter and the passing air is carbureted by spray ation.

By the arrangement and construction herein shown and described, a proper carburization of the slowly moving volumes of air is insured, while an excessive carburization of the rapidly moving volumes of air is prevented, and a uniform mixture obtained for the various speeds of the motor.

We desire it to be understood that other forms of deflectors could be devised, without departing from the scope of this present invention when having the teachings of this I disclosure at hand, and we do not therefore limit ourselves to the specific form here shown.

In the form of deflector here shown, the air In this form, the proper size of seems passage is made rectangular at the point where the deflector is located, and the deflector will fit it sufficientl snug to prevent any ap reciable passage of air past its sides. To ena le the insertion and removal of the deflector, the passage is rovided. with an ppening 10 and a removab e cover 11' there- A valve or throttle 12 is located in the outlet end or portion of the air passage, which when partially closed, causes the air tapass the oil inlet relatively slow, and the deflector restricts the air assage and causes these slowly-moving vo umes of air to pass close to the oil inlet 2.

Having thus described this invention, what is claimed and desired to be secured by Letters Patent, is

1. A ca'rbureter having an air assage, a

fluidinlet therein means ada' te to mamtain a body of volatile fluid t erein for surface carburization of slowly moving volumes of air and the fluid inlet restricted to cause spra carburization of rapidly movin umes of air, and a movable air de ector within the air passage-way adapted to direct volthe slowly moving volumes of air downward against the said maintained body of fluid,

and to be lifted by the rapidly movable volumes of air for spray car urization thereof.

2. A carbureter having an air passage provided with a fluid inlet in its bottom, means for maintaining a body of volatile fluid therethrough in the bottom of the passage by gravity flow for surface carburization of slowly moving, volumes of air, the inlet so restricted as to require suction of the. fluid through the inlet for spray carburization of the rapidly-moving volumes of air, a deflector within the air passage and freely movable in the direction of the air through the assa e said deflector havin an o enin adb D b jacent the body of fluid for the slowly-moving volumes of air, and adapted to swing open under the influence of the rapidly-moving volumes of air.

In testimony whereof we affix our signatures in presence of two witnesses.
